For sale is this nice, Vintage Gold Filled Picture Agate Pin. It measures 1 3/8" x 1 1/8" and has a quality clasp and absolutely no damage or repairs. It weighs 10 grams and although the frame tests as 10k gold, I believe it simply has a heavy solid gold plating. It is not marked and dates to the 1960's.
